Who Studies outer space the solar system and objects on it?
astronomers
How is venus related to astronomy?
It's an object in outer space; that's basically what astronomy is about - studying objects in outer space.
What is the definition of being in space?
Being in space refers to being outside Earth's atmosphere, typically at an altitude above 100 kilometers. In space, there is a vacuum, no atmosphere, and weightlessness due to the absence of gravity, which allows objects to float freely.
How does motion occur in outer space?
Motion in outer space occurs through the interaction of gravity and the initial momentum of objects. Once set in motion, objects in space will continue to move in a straight line unless acted upon by another force (such as gravity from a planet or star). The absence of air resistance in space allows objects to travel at constant speeds and maintain their velocity until another force intervenes.
Can vacuum create weightlessness?
A perfect vaccuum is one in which there are no molecules of anything in it. That means no atmosphere, no nothing. But, that has nothing to do with the effects of gravity. Outer space is very close to being a perfect vaccuum but still experiences gravitational fields; if it didn't the Earth would be flung out in nothingness.
How would you explain the weightlessness of abjects in outer space?
The force of gravity decreases as distance from the center of the gravitational field increases. Objects in outer space are generally millions of miles from the closest massive source of gravity, which makes them seem weightless. In reality, their weight is existent, but extremely close to zero.
How do astronauts describe the position of objects in space?
Weightlessness.
Will one ton float in outer space?
No, one ton would not float in outer space because weightlessness in space is due to the absence of gravity, not because of buoyant forces. In space, objects with mass will still have weight but will appear weightless due to the lack of a gravitational force pulling them down.
What is weightlessness in space?
Weightlessness in space refers to a condition where objects and individuals experience a sensation of being weightless due to the absence of gravitational forces. This occurs when objects are in freefall towards a massive body, like Earth, allowing them to float freely inside a spacecraft. Despite the feeling of weightlessness, the force of gravity is still present, but all objects fall at the same rate due to being in orbit.
What is a state of very weak gravity called?
A state of very weak gravity is called microgravity. In this condition, objects experience little to no gravitational force, typically encountered in outer space or during freefall.
What does weightlessness?
Weightlessness is the effect that astronauts enjoy in space.
What does weightlessness mean?
Weightlessness is the effect that astronauts enjoy in space.
How do you put weightlessness in a sentence?
In space, there is no gravity and one would experience weightlessness.
Can people be weightless if so how and where?
People are weightless if in zero gravity in outer space. On earth, weightlessness can be simulated for training in a rapidly descending aeroplane.
Why can you be weightless?
You can be weightless when experiencing free fall, such as in an elevator dropping or skydiving, because you are in a state of apparent weightlessness due to the force of gravity acting equally on you and the objects around you, causing you to float. This sensation occurs when the acceleration from gravity counteracts the force of gravity pulling you downwards, creating a feeling of weightlessness.
How does weight change in space?
In space, weightlessness occurs because there is no gravity acting on objects. As a result, objects and astronauts float freely without feeling the sensation of weight. This is different from mass, which remains constant regardless of location.
What the source of light is for bright objects in outer space?
Stars
